TUBE COMPRESSOR.

Application filed June 14,

This invention relates to compression clamps adapted to be manually operated and to be applied to a rubber or other compress ible tube whereby the circulation of a liquid through the tube may be permitted or discontinned at Will.

The invention is an improvement'on the type or tube compressor described and illustrated in the patent to A. J. Frey, No. 1,297,456, dated March 18, 1919, and although it is not to be limited to the specific construction of compressor shown in the patent, it may be applied equally advantageously to all compressors of the same general type of the patent.

The principal object of the invention is the production of a tube compressor having a hook thereon enabling the user to hang the compressor on the mouth of a bag when not in use.

A further object of the invention is the production of a compressor of the above type in which the hook is formed 01' the metal usually cut out to form an opening through which the tube passes for engagement by the clamping aws.

Referring to the accompanying drawing showing a practical embodiment of the invention:

Fig. 1 is a perspective View of the tube compressor showing it applied to a rubber tube or hose.

Fig. 2 is a section through the. compressor.

Fig. 3 is a plan view thereof.

Referring in detail to the drawing:

1 and 2 represent the clamping jaws preferably formed of a single piece of sheet metal provided with an opening 3 for the insertion oi a tube 4 to be clamped by said clamping 1928. Serial No. 285,5;"7.

jaws. 5 and (3 indicate brackets rising from the base and preferably integral with the jaw 1. Said brackets are provided near their upper ends with openings 7 receiving pintles 8 extending from a cam piece 9 and pivoted in said openings.

The cam piece 9 is provided with two actuating arms 10 and 11 to compress the clamping jaW 2 or release the same. The arms are preferably formed of a single strip of sheet metal preferably integral with the cam piece 9. To secure an elfective pressure or" the cam piece 9 on the jaw 2 by the operation of arm 10 a strut 12 is cut out of the metal from one member of the structure forming the cam and operating arm which 5 extends from the cam near its engaging end back to the actuating arm 11.

When forming the opening 3 for reception of the tube 4 I avoid any waste of metal by bending the cut out portion which forms the opening over into a hook 13. Therefore when the device is not in use, rather than a dangling long length of tube, the tube may be looped and the hook 13 engaged on the mouth of the bag forming the source of liq- 6 uid supply or it may be engaged with any other convenient object.

I claim:

A sheet metal tube compressor having an opening therein for receiving the tube, a pair of clamping jaws, operating means therefor anda hook formed of the metal which has been removed from the compressor to form said opening.

Signed at Brooklyn, in the count O'l Kings, and State of New York this 12th day of June, A. D. 1928.
